ISLAMABAD: PTI on Sunday criticised authorities over the reported failure to conduct a recommended cardiac CT angiography (CTA) on jailed founder Imran Khan. He was taken to Pims on Friday for an eye procedure and diagnostic tests, but reportedly returned to Adiala jail without undergoing the scan. The party demanded the test be performed immediately at Shifa International Hospital. Doctors said PIMS radiology department has equipment capable of conducting CTA.
